Clean healthy foods all year long. I almost never eat sweets, I really do not like them, fast food smells like garbage to me so it is fairly easy to eat clean. Bulking means lots of meat, eggs, milk and fresh vegetables the key to bulking for me is constant grazing, not high calorie junk foods. Stay away from most fruit juices they are loaded with sugar so I consider them junk food. The less processed your food is the better it is.
